I'm converting the driver to use mfd_add_devices and
mfd_remove_devices, the subdrivers will access the parent's private
data which will remain valid since in the remove method we will be
calling mfd_remove_devices first.

After removing all global calls to twl-core.c methods, I will also get
rid of the "only one instance" of twl_priv and the "ready" flag.

Thanks for your input,
Nicolae
